rially aflect the pressure of the valve against the valve seat, as the springs will sufiiciently yield to compensate for such pressure. The

valve seat and valve casing are held in po- 4.0 assure against leakage at this point. The

extreme outer end of the valve controlling sleeve is bifurcated to receive a universal joint 78 to which is attached a rod 79 for controlling the rotating movement of the valve sleeve and this rod can be extended to any suitable point for ready manipulation.

As the crank case is to be filled with hi bricating oil and in View of the fact that the rapid rotation of the crank within the case causes the oil to expand, I provide an expansion chamber or cup 80 which is connected to the interior of the crank case by means of a pipe 81 so that when the oil within the crank case expands it will pass through the pipe into the expansion chamher; As the oil is consumed in the crank case an additional supply is fed into the crank case from the expansion chamber and as the pipe is smaller than the expansion chamber the oil will be gradually fed into the crank case from the expansion chamber. 'Asthe upper end of the expansion chamber is left open in order to prevent a vacuum within the crank case, a strip of fine wire gauze 82 or similar substance is placed overthe upper end of the expansion chamher to exclude dirt and the like from the oil. As the expansion chamber is located above the crank case, it can be used for introducing the oil into the crank case when a new supply is necessary. By arranging the cylinders in the manner shown and providing a single-valve for changing the device from a driving motor to a pump it can be constructed in compact form and at a minimum expense. It will likewise be seen that the device can be used for starting internal combustion engines, or by arranging any suitable means toroperating the pistons when used as a pump to resupply the tank, the motor can be used for driving machinery or similar objects and it will likewise be seen that the valve can be instantly changed from one position to'the other to provide a driving motor or a pump, as occasion may require and at the same time not affecting the rotation of the crank shaft or the movement of the pistons.

What I claim is l. in acombined motor and pump the combination with a plurality of cylinders having pistons therein and ports commun1- catnip; wltlrzsaid cylinders, of adisk-like valve having a groove in one face thereof means to cause said valve to rotate with the plate and yielding means between the plate and valve to hold said valve in proper relation adjacent the ports.

2. In a motor the combination with a plu'ality of cylinders and pistons in said cylinders, of a valve seat having ports therein, a disk-like valve cooperating with said seat, a plate having a sleeve upon which said valve is mounted and yielding means between the plate and valve to hold. said valve in proper relation adjacent the ports.

3. In a' motor the combination with a plurality of cylinders having ports communicating therewith, of a: rotating valve cooperating with said ports, a plate having a sleeve thereon, upon which said valve is mounted, means to cause the valve to retate with the plate, springs between the plate and valve to yieldingly hold the valve adjacent the ports and means to manually rotate said valve.

4-. In a combined motor and pump the con'ibination with a crank case, a crank shaft projecting through said case, a plurality of cylinders arranged around said case, pistons in said cylinders and connected to the crank portion of the shaft and a,valve seat having ports therein arranged inpairs, one of the pairs of ports communicating with one of the cylinders at its outer end and the other port communicating with thcouter edge of the seat, of a valve rotatable with said shaft having a channel in one edge adapted to cooperate with certain of said ports and a groove in one face of the valveto cooperate with others of said ports, means to yield ingly hold the valve adjaccntnthe seat, a locking bar adapted. to normally hold the valve against indcpendentrotation of the crank shaft, means to automatically release the locking bar from the valve and simultaneously engage? the valveand rotate the same independently of the shaft.

5. In a motor the combination with a plurality of cylinders, pistons cooperating therewith and a crank shaft connected to the pistons, of a valve seat having ports arranged in pairs, one end of said ports communicating with one face of the valve seat, the opposite ends of one of each set. of ports conm'iunicatingwith the cylinders and the same end of the remaining ports with the outer edge of the valve seat, a valve carried by the crank shaft having a channel in one edge adapted to register with the inner ends of certain of the ports comto I municating with the cylinders and having a recess in one face adapted to register with the inner ends of certain of the pairs of ports whereby propelling medium will 'be introduced into the ports registering with the recess and the ports connnunicating with bar from said notches, means to cause said sleeve to move lengthwise when rotated and teeth on the inner end of the sleeve adapted tov engage the teeth of the valve and rotate said valve when the locking bar is released from the notches. V

7. In a motor the combination with a pluralit-y of cylinders and a crank shaft, of a valve mounted upon said shaft, the wall of the opening through which the shaft extends having notches therein, a locking bar adapted to alternately engage said notches to hold the valve in fixed relation with the crank shaftand means to automatically release the locking bar and rotate the valve.

8. In a motor the combination with cylinders, 'a crank shaft and a valve mounted upon said shaft, the wall of the opening in said valve through which the shaft extends having notches'therein, of a spring operated locking bar adapted to alternately engage said notches to hold the valve in fixed relation with the crank shaft.

9. The combination with a motor comprising a plurality of cylinders having ports, of a valve cooperating with said ports, a plate having a sleeve upon which said valve is mounted and springs/carried by the plate and between the plate and valve adapted to direct pressure against the valve and hold the same in close relation with said ports.

10. In a motor the combination with a plurality of cylinders, pistons in said cylinders and a valve cooperating with the cylinders, said valve having teeth thereon, of a tubular sleeve having teeth adapted to engage'the teeth on the valve, means to rotate said sleeve and additional means to move the sleeve lengthwise to engage the teeth with or disengage them from the teeth of the valve.

11. In a motor the combination with a plurality of cylinders and a valve cooperating with the cylinders, of a tubular sleeve, means to move the sleeve toward or from the valve, means to cause the valve to rotate with the sleeve, a latch adapted to hold the valve in adjusted position and means on the sleeve to engage and release the latch when the sleeve is moved inwardly.

12. In a motor the com'binationavith cylinders and a rotating valve cooperating therewith, of a tubular sleeve adapted to engage and rotate the valve, said sleeve having a slot extending circumferentially thereof, the ends of which slot are curved forwardly and a pin engaging said slot to cause the sleeve to move lengthwise when the sleeve is rotated.

13. In a motor the combination with cyl-v inders and a valve cooperating therewith,

of a tubular sleeve having a circumferential slot therein, the ends of which slot are curved inwardly, a pin engaging said slot to cause said sleeve to move into" and out of engagement with the valve when the sleeve is rotated, said valve and inner end of the sleeve having interlocking means thereon, whereby thevalve will be positively rotated when the sleeve is rotated. i

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
